One of the things I noticed, is that the first time around, Iori has a personality problem, and they switch personalities and was trolled into believing her life was threatened. Second time around, Inaba has trouble trusting others and has low self esteem, which leaves her unable to pursue what she desires the most, and they all act out their desires spontaneously and was trolled into believing Taichi fell off a cliff. Thirdly, Taichi, has a problem white knighting, so everybody else turns into kids (which brings up memories from that time, whether they were good or bad), and I'm guessing he's being trolled that he can't tell the others that he knows what's going on, because otherwise he probably can't really help them the way he wants to or something.

There also seems to be one more arc after this current one, though that leaves 4 out volumes of the light novel, so here's hoping for a second season sometime in the future.
